Order Book Randomization

Algorithm

Order book randomization represents a deliberate alteration of the sequence of limit orders within an electronic exchange’s order book, typically implemented to mitigate the impact of predatory trading strategies or to enhance price discovery. This process, often employing pseudorandom number generation, aims to disrupt predictable order placement patterns exploited by high-frequency trading firms. Effective randomization seeks to introduce stochasticity without unduly impacting legitimate market participants or increasing adverse selection. The implementation of such algorithms requires careful calibration to balance fairness, efficiency, and regulatory compliance within the specific exchange environment.
